Connecting to Legacy AFP services

I can't seem to get this to work under Mountain Lion although it works fine under Lion. http://support.apple.com/kb/HT4700?viewlocale=en_US&locale=en_US

When I try Step 4, I receive the following error, The domain/default pair of (/Library/Preferences/com.apple.AppleShareClient, afp_disabled_uams) does not exist

I am attempting to connect to NetWare 6.5, SP8 using clear text.

OS X Mountain Lion (10.8.1)
